Iron sulfate is often offered to combat it, it is cheap and seems to work quickly. Appearances are deceptive, however, because iron sulphate is extremely corrosive and is harmful to human and animal health. It also makes the soil acidic - good for the moss and bad for the lawn. It is better to use sulfuric acid ammonia.

What is sulfuric acid ammonia anyway?
Sulfuric acid ammonia is not a weed killer, as one might suspect, but a fertilizer that contains ammonium nitrogen and water-soluble sulfur. The combination of these two substances ensures that the fertilizer is not easily rinsed out even with persistent moisture and enriches it with nitrogen and sulfur. This promotes the growth and health of the lawn and moss or clover no longer have a chance or a livelihood.
What should I watch out for when using sulfuric acid ammonia?
Sulfuric acid ammonia lowers the pH value in the soil, so it should only be administered if the pH value is too high or in the upper normal range. If the soil becomes too acidic, grasses grow less well, but moss or clover grow better.
Therefore, it makes sense to test the pH of the turf soil before administering sulfuric acid ammonia. This test should also be part of regular lawn care in spring. Then you can react before moss spreads on your lawn.
What else can help my lawn?
Provide as much sun as possible on your lawn, then the lawn grasses will thrive much more vigorously. Ground cover is much more suitable than lawn for shady and damp garden corners. Perhaps rethink your garden planning.
The essentials in brief:
- do not use toxic iron sulfate
- Test the pH of the soil
- Use sulfuric acid ammonia in a targeted and well-dosed manner
- Loosen moss by scarifying
- Drain the soil if possible
- no shady plants on the lawn
Tips
Moss is particularly at home on damp ground and in the shade. If you deprive it of its livelihood, your lawn will grow better.
